Abstract
The use of adsorbents in cigarette filters guarantees a substantial reduction of volatile and semi-volatile smoke components. We added adsorbents to the sheet tobacco and then analysed the effect on the composition of the smoke. The results show a substantiaI reduction of many smoke components when 10 % to 18 % of a special meerschaum quality as fine powder is stirred into the slurry before drying. Addition of 10 % meerschaum results in a reduction of about 30 % for nicotine and dry condensate as well as for semi-volatile substances (phenols, cresols, scatol, etc.). With an 18 % addition the reduction is about 45 % compared to sheet tobacco without meerschaum. This significant diminution of some of the undesirable smoke components is achieved without any impairment of the aroma of the smoke.
